, p. 5616 - 5619 (2017)
The conversion of SO2 into arylsulfones under metal-free conditions was achieved for the first time by reacting SO2 with (hetero)arylsilanes and alkylhalides in the presence of a fluoride source. The mechanism of this transformation was elucidated based on DFT calculations, which highlight the influence of SO2 in promoting C?Si bond cleavage.
Catalyst-Free Sulfonylation of (Hetero)aryl Iodides with Sodium Dithionite

The commercially available and cheap sodium dithionite is used as the source of sulfonyl group for the synthesis of sulfones and sulfonamides from (hetero)aryl iodides under catalyst-free conditions. During the reaction process, sodium sulfinates generated in situ are the key intermediate, which can be further converted into diverse sulfones and sulfonamides. This transformation proceeds through a radical process initiated by sodium dithionite, providing a convenient route to sulfonyl-containing compounds. (Figure presented.).
